RAZGE-STRGPPH DE Application T 0 all whom it may concern:

Be it known that l, ELMER l. Yours, a citizen of the United States,residing at Montclair, in the county of Essex and State of New Jersey,have invented anew and ful Razor-Shopping Device, of which the followingis a specification My invention relates to improvements inrazor-stropping devices, and more particu- 19 larl to devices forshopping razor blades use in safety razors.

The objects of my invention are, first, to provide a stropping devicesimple in its construction, but positive in its action; second,

a stropping device in which there is no mechanism intermediate of thefriction-roller and the blade-holder; third, to provide a.strepping-de'vice adapted to strop blades oi any thickness, with orwithout backs; fourth, to

20 increase the surface of contact between the friction-roller and thestrop; andfifth', a stropping device that can be quickly and easilytaken apart OT assembled.

Further and other objects will more definitely appear from the detaileddescription to follow.

I accomplish the objects of my i"ention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is illustrated in theaccompanying drawings, forming a part of this specific-a tion, in which-Figure l is a top View of my improved shopping-device, showing arazor-blade held in one stropping position by the bladeholder. Fig. 2 isa side view. 3 is an end view, showing a razor strop and blade in situ.Fig. 4t is an enlarged perspective view of an auxiliary blade-holder.

In the drawing: similar letters of reference refer to similar partsthroughout the several views.

Referring to the drawings, the frame of my improved razor-shoppingdevice consists of a base-plate A and parallel standards I) D rigidlysecured thereto,-said standards 1) 1) being connected to each other bythe member I) and adapted to support a strep S. The base-plate A-ispreferably formed from sheet metal, suitably shaped by bending the metalover upon itselfand bringing 5 the ends together at right angles theretoto base-plate i1 etporl van. a

I irevoluel mounted the blade-bolder l while uon the spindle l is revolubly mounted s trim to. tion-roll'er (5,preferably made or rubber, though any other suitable material may beused. Suitable means are provided for actuating the bladc-hohler by theroller C In the best embodiment of my invention, 1 arrange the spindlesE E adjacent to each other, so that the roller G will be in trictionalcontact with tho blade-holder and the travel of the blade will be awayfrom on either side or the roller .2. As shown in the u" drawings, iprefer to form the two swindl. it E integral with the connecting pi andreniovably secured to the base-plate A in a plane perpendicular to theplane o." standards D l The en s E pass through the base-plate clampin.nieniber C, where they rigidly e v a screw ll which.

es the notches r lower surface oi the roller u, so tl at w. the strop 5passes over "the standa ds D E and under the roller G, it will tend. toenvelop the roller G and thus largely increase the surface ofcontactbetween. the roller G and the strep. As the device is moved overthe strap, the base plate A will act a guide, thus keeping the rollerand blade- 10 holder transverse to the strep.

The blade-hol ler l may be of any desired construction adapter totirinly hold a razor blade K. While bein, stropped. As shown, theblade-holder if is provided with two 10 spring which are adapted toreceive-and hold firmly the back is of the blade K. l Vhen it is desiredto strep blades having no backs, I provide an auxiliary blade-holderformed from strip of s metal bent over upon itself and having edges Z Zto engage the blade, entrance of the blade. This auxiliary bladeholder Lis adapted to be inserted in the blade-holder F and to be heldiirmly bythe jaws f f.

My improved stropping device is adapted to be used With the ordinary andwell-known form of strop, which usually is a strip of leather. Asindicated in Fig. 3, the strop S runs over the two standards D D andunder the roller G. As the stropping-device is moved backward andforward, the friction of the strop upon the roller G causes the latterto rotate upon the spindle 1G and directly actuate the blade-holder 1which will hold the blade K against the strep at the proper angle forstropping. As soon as the movement of the device over the strop isreversed, the roller G will reverse it rota tion 'hnd cause theblade-holder F to oscillate or reverse and assume the dotted positionshown in Fig. 3. By removing the screw 11, the spindle E E can bewithdrawn from the base-plate, in order to receive a new bladeholde oranew friction-roller if desired, and tie handle B can then be withdrawn.The parts can be reassembled in the reverse order.

While I have shown and described a device embodying my invention in theform preferred by me, yet it is capable of consid erable structuralvariation without, however, departing from the spirit of my IRVQHUOILWhat 1 claim as new, and desire to secureby Letters Patent, is:

1. In a razor-stropping device, the combination of a base plate adaptedto guide the strep, a handle secured thereto, for imparting bodilymovement to the device, a
